Does anyone have a list of various road fork lengths? I did a search for a list but was too lazy to go beyond 15 pages... :)

I was tracking this info on my own for some time but switched from a PC to MAC and lost a bunch of data including my list. Understanding that this question comes up from time to time it would be great to compile the information here.

Serotta F3/S3 (assuming they're the same) = 372mm (updated)
Serotta F2 = 373mm (added)
Serotta F1 fork = 365mm (added)
True Temper Alpha Q = 371mm
Edge/Enve = 367mm (updated)
Mizuno = 375mm
Reynolds Ouzo Pro, Pre 2004 = 370mm, Post 2004 = 372mm (updated)
Wound up = 366mm
Easton = 365mm
Bontrager Race X-Lite = 379mm

Interesting info from Sheldon Brown's site:

Please update and add. Thanks.

Am I thinking correctly here - if you keep fork rake the same:

longer fork = shallower (decreased) head angle = more trail
shorter form= steeper (increased) head angle = less trail

or do I have it backwards?

You have it right. But 3 or 4mm of length is going to change the trail by only 1mm. You'd have to go from one extreme of length to the other before HTA and trail are really impacted in a significant way.

Bontrager Race X Lite is 371mm. I think Bontager (Trek) all have the same length except the models made for long reach brakes.

I believe the Serotta F1 fork was 365mm.

A while back Mike Lopez confirmed that the span of the F3/S3 is 372mm.

Also, iirc, the span of the Ouzo Pro until 2004 or so was 370mm. A different dropout changed the span to 372mm. I think that the F2 was also 370mm.

Why are there so many different lengths?

The build sheet for my 2004 Ottrott shows my fork span (F2) to be 37.3cm

Thanks for all of the updates. I have inserted the revisions in the first post of the thread.

As for this question, I am curious too.
